Readers offer their best tips for not missing too many important calls, a handy set of neck exercises, and blocking spoilers in Amazon Prime TV/Movie descriptions.

Every day we receive boatloads of great reader tips in our inbox, but for various reasons—maybe they're a bit too niche, maybe we couldn't find a good way to present it, or maybe we just couldn't fit it in—the tip didn't make the front page. From the Tips Box is where we round up some of our favorites for your buffet-style consumption. Got a tip of your own to share? Add it in the comments, email it to tips at lifehacker.com, or share it over at our user-run blog, Hackerspace.

Important Call Alerts You After Too Many Missed Calls or Texts

Nick shares this Android app that alerts you after a set number of missed calls or texts:

Sometimes I leave my phone on vibrate and forget to turn the sound back on. This can mean missing important calls or texts. The Important Call app (free for Android) sounds an alarm when you've missed a certain number of calls or texts. You set the number it's okay to miss and the alarm sound and volume (which will sound even if your phone's on vibrate).

Use These Handy Neck Stretches when You're Stuck at Your Desk

Dina shares a web site that guides you through a quick series of neck stretches:

I've read about different stretches and exercises you can do for your neck after you've been sitting at your desk for too long, but I always forget to do them and have to look up how. I found this site that guides you through some simple stretches you can do at your own pace. I just stuck the link on my Bookmarks toolbar so I remember to do them.

Use AdBlock to Block Spoilers from Amazon Prime Descriptions

I like to watch TV shows on Amazon Prime Instant Video. But, sometimes the descriptions of the episodes contain spoilers about the episode. I turns out you can adjust your AdBlock settings to hide them. Just right-click the description and choose Block this ad from the AdBlock menu. Use the slider to adjust the amount of blocking. You should be able to get just the description blocked. And if you want to see them, it's easy enough to reverse or just pause blocking on the site.

Build this Cute Cable Holder for your Desk

Benny shares a tip for making a rather cute cable holder for the back of your desk:

I hate when I unplug a gadget and the power or USB cable for it falls behind my desk. I know there are commercial products designed for this and of course there's the famous Lifehacker binder clip solution. But I wanted something a little different. It's simple enough to make and you could easily cut out a different shape.
